OAKLAND — A 17-year-old girl was shot and killed Thursday afternoon at a Chinatown apartment building, and her family later pleaded publicly for her 14-year-old brother to turn himself in safely after police said they believed he was linked to the slaying.

The shooting was reported shortly after noon in a fifth-floor unit at 801 Franklin St., police said. The victim was pronounced dead at the scene; family members identified her as Justice Toliver, mother of a 2-year-old daughter.

Police did not release a description of the 14-year-old brother who is wanted in the shooting, but family members issued a public plea for the boy, Mario Toliver Jr., to turn himself in peacefully.

“I love him, no love is lost,” said the children’s grandmother, Wanda Brown. “I know he’s hurt right now, and I know they were bickering, but they were like two peas in a pod.”

Cousin Gregory Stewart, 25, added: “If you know him, if you see him, we just want him to come home. We know he’s probably scared. We love him.”

Brown said the two had grown up in the Chinatown apartment with their father, that they loved to go shopping or to the movies, and that they often sang and played baseball together. Their father, Mario Toliver Sr., was not home at the time of the shooting, but another grandparent was and called for help.

Police have not yet released a motive in the killing, the eighth homicide in Oakland this year.

However, several family members said the two had an argument because the girl bleached some of her brother’s clothing.

“They got into some type of altercation,” Stewart said. “Whatever it was about it shouldn’t get that serious to pick up a gun and kill his sister.”

Family members said Mario Toliver Jr. is a black male, 14 years old, 5 feet tall and slender, with black hair and brown eyes, and was last seen wearing a black hooded sweatshirt. He is on foot.

Dozens of residents of the multi-story apartment building were kept from entering their homes during the investigation.

The investigation is ongoing and anyone with information is asked call the Oakland Police Department’s homicide unit at 510-238-3821 or Crime Stoppers at 510-777-8572. There is a reward of up to $10,000 for information leading to the arrest of the suspect.
